The South Korean government has granted approval to begin construction on the world’s first “invisible” tower.

Designed by U.S.-based GDS Architects, the glass-encased Tower Infinity will top out at 450 meters (1,476 feet) and have the third highest observation deck in the world.

The project is backed by Korea Land & Housing Corporation, a state-owned land and public housing developer.

The invisibility illusion will be achieved with a high-tech LED facade system that uses a series of cameras that will send real-time images onto the building’s reflective surface.

It will be built just outside of Seoul near the Incheon International Airport.

Neither the developer nor GDS have released a target completion date.

The development will reportedly be used primarily for leisure activities. It will include a series of observation decks, a movie theater, roller coaster, water park and numerous food and beverage outlets.

Though height isn’t its main selling point, Tower Infinity is no slouch in the vertical department.
